Luckily Barcelona can give their best performance in this match and finally you win in this gambling. We all know that Barcelona often lost in previous matches. So that experience makes you realize that you have to accept the risk of failure. Finally, Barcelona managed to give victory to its supporters from Fermín López's kick in the 59th minute, this was quite a good development for Barcelona.
That change nothing, whether they won that game or not since Barcelona will have a new manager and new strategy and eventually players will join them (for free as usual?) then they blame the coach for not winning anything (surprise!).
At least they ended the season in the second place..
Valladolid and most likely Leganes will move to La Liga and replace Granada, Almeria and Cadiz. The third team to promote will be determined later after play-offs.
At least Barcelona can finish in runner up position after a series of unsatisfactory results this season and they will start next season with a new manager of course with different tactics like Cavi's, we don't know whether Barcelona's performance next season will be better or worse but if there are no changes in terms of Barca's squad, I think they still have the same strength as this but it depends on the new manager's coaching system whether it will be as good as Cavi.
Yes, they will go to La Liga 1 next season and replace the relegated clubs from La Liga 1 this season and will compete in La Liga where the competition is quite tight, only strong clubs can survive there. They have to show their best performance if they want to stay there longer and not returning to laliga 2.
